A still further object of the invention is the provision of an improved dish washing machine of the above character which is durable and efficient in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost. Y

With these and other objects in view, the invention consists in the nov el construction, arrangement and formation of parts as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part of this specification,and in which drawings:

Figure l is a front elevation of the improved dish washing machine.

Figure 2 is a side elevation of the same.

Figure 3 is a central vertical longitudinal section throughthe same.

Figure 4 is a central vertical transverse section through the same. I

Figure 5 is an enlarged fragmentary vertical section through the housing and door taken on the line 55 of Figure 1.

Figure 6 is a horizontal section through the housing showing the door in its open position, and

Figure 7 is an enlarged fragmentary vertical section through the housing'and coupling for the rotatable U-shaped members and the water supply pipe therefor.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout-the several views, the letter A indicates the improvedwashing machine which-includes the housing or casing B, the dishbasket support C, the dish basket D, and the improved. cleaning fluid ejecting device E. i

The casing or housing B can be made of any preferred materials or combination of materials, such as enamelled or galvanized iron, aluminum, copper or the like. It is preferred in the construction ,of the housing that the upper'portion thereof be constructed-of aluminum, while the lower portion thereof be constructedofheavy J apanned sheet metal, but this is merely a matter of choice. The housing or casing B consists of angled irons arranged at the corners thereof to which are suitably secured the end walls 11 and the ..front and rear wall 12 and 13. The upper portion of the housing is preferably bowed outwardly so as to increase the capacity thereof, and the upper portion is divided from the lower portion by a horizontally disposed aluminum plate or partition 14,

Y which is inclined inwardly toward a central longitudinal lin to permit the water collecting in the upper portion of the housing to readily drain therefrom. The partition 14 dividesthe housing B into an upper dish cleaning chamber '15 and a lower dish drying chamber 16. The extreme lower portion of the chamber 13 is formed relatively wide as at 17 so as to form a relatively large supporting base and the same is provided-With a bottom wall 18 which supports the casters 19. This permits the dish washing machine to be moved to any point desired. It is to be understood however that the machine may be built into a building and form a portion of the walls thereof. The rear wall 13 of the dish washing cha 'ber 15 is 01 ved as at 20 and terminates in a horizontally disposed upper wall 21.

The dish basket support C is arranged in the dishv washing compartment 15 and includes a centrally disposed transversely extending beam 22 held in place by suitable angle brackets 23. v The transversely extend ing beam or bar 22 carries at equi-distantly spaced points the oppositely projecting arms 24, the terminals of which have bolted or otherwise secured thereto the tracks or of the dish support C is such that a broad side entrance or exit of the dish basket D is guides 25 for the dish basket D. The arms 24 maybe secured to the beam or rod 22 in any preferred manner, such as by angle brackets 26 or the like. The arrangements permitted. This allows the convenient and easy removal and placing of a basket in the washing chamber. This arrangement of the support also permits the washing machine to be in any length.

The dish basket D is preferably formed of woven wire so that the water or other cleanand thereby permit the dishes held therein ing fluid will readily pass through the same to be acted upon by the cleaning fluid.

.However, it isto be understood that. thegj .di'sh basket C. may be made out of any reticulated material. v

5 The improved cleanin" fluid ejectlng device E consists of "a pair of'substantially I usshaped' members 27, the arms 28 of which are disposedin a horizontal. plane and terminate adjacent to each other and the trans-, w

verse axis the housing. The space between the terminals of the arms is just suflicient to accommodate the transverse beam or bar 22. This permits the rotation of the U-shaped members 27 in the dish cleaning compartment 15 as will be hereinafter more fully described. The bi'ght portion 29 of each U-shaped member 27 has the central part thereof connected by a T-joint 30 and coupling 31, which will be hereinafter more fully described, to the end walls of-the casing. The arms 28 are bent to form a plurality of angularly related portions 32, and the arms are provided with a plurality of apertures 33 provided for the exitof the cleaning fluid. The stem portions of the T-j'oints 30 form means for rotatably supporting the U-shaped members. It can be seen that certain of the apertures 33 are positioned to project sprays tangentially of the path of rotation, and the forcible exit of the water from the arms acting upon the air rotates the members on the stems. The arms '28 are bent to form a plurality of angularly disposed portions 32 so that the water or other cleanin fluid will leave the same at different ang es and thereby act on all portions of the dishes contained in the dish basket D during the rotation of the members.

Each coupling 31 includes an externally threaded sleeve 34, which is held inplace on the exterior of the housing by an internally threaded coupling 35 which is bolted or otherwise secured in position. This sleeve 34 rotatably receives the stem of the T-joint 30 and the same is held against withdrawal from the sleeve by means of a nut or the like 36 which is threaded on the outer end of the stem. The U-shaped members 27 are held in spaced relation to the inner surface of the side walls of the housing by spacing elements 37 which are bolted or otherwise secured to the side walls. The sleeves 34 have threaded thereon the nipples which 'the same may be connected with a -suitable supply pipe, so that hot water or other cleaning fluid may be forced therein. One of the side walls 11 is provided with an outlet opening 42"which is. in direct alignment with the longitudinal center of the partition 14.. This outlet opening serves as a means for permitting water to drain from the dishwashing chamber 15.

.The front wall 12 of the casing B is providcd with a relatively large opening 43 which connects with the interior of the cleanin chamber 15 and this opening 43 is adapte to be closed by a door 44, which is held in place by suitable hinges 45. The door is adapted to be swung to a horizontal position as clearly shown in Figures 4 and 6 of the drawings and the links or arms 46 are provided for holding the door in such position. The links or arms 46 are provided with lower angled terminals which are pivotally connected to cars 48 carried by the front wall below the opening 43. .The upper terminals of the arms 46 are also angled and forked as at 49 and the forked terminals embrace the opposite sides of outwardly extending slotted guides 50 secured tothe outer face of the hinges 45, which extend entirely across the face of thedoor for a purpose which will hereinafter more fully appear. The angled terminals 49 of the links or arms 46 carry pins 51 which are slidably mounted in the slotted guides 50. The door 44is provided with a glass panel 52 so that the ac: tion of the water on the dishes may be readily seen. The inner surface of the door 44 carries guidesor tracks 53 and these guides or tracks are in direct alignment with the lower chamber is providedwith a guides or tracks 25 carried by the outstanding arms 24. The guides or tracks 53 extend below the lower edge 9f the door 44 and when the door 44is swung to its horizontal position the lower terminals of the track 53 with This placing of the are brought into alignment and flush the upper surface of the tracks 25. permits the. ready removal or basket on the support C.

The lower dish drying chamber be provided with suitable racks 55, reception of dishes or otherarticles 16 may for theand the pair of doors 56 which are hingedly secured to the front wall 12; I

The end walls 11 are provided with end rails 57 which maybe formed of any preferred' material. These end rails 57 are lo v cated intermediate the ends of the machine,

so that the operator thereof can readily push the machine to any portion of a room.

Tn operation of the improved machine, the door 44 is. swung to its horizontal position as clearly shown in Figures 4 and 6 of'the drawings and held in that'position by the? arms cr -links 46- and the basket D with the dishes is then placed-on the tracks; 53 andpushed into the interior of the compartment 15. The door 44 istherrswungto its closed position and held in said position b any suitable or preferred type. of lockgwnot shown). The cleaning fluidxis then permit ted to flow through-5 the pipe'4l, from whence it will flow into the" ll-shaped members 27 into the arms 28. The water leaving the 4 arms will f rotate the U-shaped members 27 v and the water brfother cleaning flui n be forced against the'dishes in the basket and thus thoroughly clean the same. It can be seen that.by the arrangement of the U- shaped members in the cleaning chamber the basket is completely subjected to a shower of the cleaning fluid which strikes the same at all angles. The arms 28.0-f the til-shaped members 27 are permitted topass entirel around the basket D and the support owing to the fact that asingle centrally dinposed transverse supportin bar is provided for securing the support 5 to the housing. When the dishes have been thoroughly cleaned the door 44 can be lowered to its horizontal position and the basket of dishes removed from the housing. The same can be placed on the members 55 in the comp-artments 16 if so desired.

From the foregoing description, it can be seen that an improved washing machine is provided, which is so constructed that the dishes to be cleaned are subjected to a continuous spray of water which is thrown against all portions of the same and the means provided for projecting the cleaning fluid against the dishes will be operated by the action of the cleaning fluid leaving the same. 1 Changes in details may be made without departing from the spirit or scope of my invention; but,
